The Blaugrana stand-in coach says he is unsure of when the Argentine will be available for selection but will wait on his fitness for the clash against les Parisiens

Barcelona coach Jordi Roura says Lionel Messi is unlikely to face Mallorca this weekend but will wait to assess his fitness ahead of their Champions League second leg against Paris Saint-Germain.

La Liga's top goalscorer was replaced at half-time during their European tie with PSG this week and has been receiving specialist treatment to ensure his readiness for next week’s conclusive quarter final.

The 25-year-old is suffering from hamstring problems and his assistant manager is not sure if he will be able to play at Camp Nou on April 10 against les Parisiens.

"It's difficult to say," the Spanish coach told reporters. "We'll see what state he's in by Wednesday. For the game tomorrow, logically, his chances are low."

Ahead of their Liga game against Mallorca this weekend, the Spanish coach said that the team are fully focused on securing the title and hinted that the Catalan club could see its line-up shuffled.

"Clearly, we have to try to find the balance [with rotation]," he added. "I've always said, and this is no exception, that La Liga is very important to us.

"We have to be focused on the match tomorrow."

The 45-year-old coach refused to comment on the refereeing at Parc des Princes on Tuesday, which Barca spokesman Toni Freixa had criticised earlier this week.

"Freixa perfectly explained the position of the club," Roura added. "He explained it perfectly and we agree."
